CAR CONSTRUCTION.

Application filed. January 8, 1923. Serial No. 611,247.

T 0 all whom it may concern: Other objects of the invention will more Be it known that I, \VILLIAM H. MINER, clearly appear from the description and a citizen of the United States, residing at claims hereinafter following. U Chazy, in the county of Clinton and State In the drawings forming a part of this 5 of New York, have invented a certain new specification, Figure 1 is a vertical transand useful Improvement in Car Construcverse sectional view of a portion of a car tions, of which the following is a full, clear, construction taken partially through the concise, and exact description, reference becenter bearing plates and showing my iming had to the accompanying drawings, provements in connection therewith.

and truck bolster locking means wherein the In carrying out my invention, I employ center plate of the body bolster is detacha body bolster center bearing castingidesigfable from the car underframe, the means nated generally by thev reference A. The employed for locking said center plate to latter is provided at its lower end with a so'jthe'underfraine being so arranged that they spherical bearing face 22 co-operable with are readily accessible for insertion and rethe truck center bearing face20. The castrnoval through openings provided in the ing A is alsoprovided with an aligned' -en- 5 f. bo dyibolster diaphragms; lter beari g or king pin open ng, an

upward extension 24 which fits within a cor respondingly shaped recess 25 provided in a bolster filler casting 26. The latter has vertical side flanges 27 2. riveted to the inner faces of the center sills and transversely extending webs 28-28, the latter having a pair of transversely extending rectangular openings 2929 therein. The center sills are apertured as indicated at 3030 opposite the openings 29 to thereby permit the insertion and removal of a pair of heavy keys 3131. The latter are made of such length that, when in operative position, the opposite ends thereof will project a short distance outward beyond the corresponding center sills, as best shown in Fig. 3. To pre vent the keys 31 becoming displaced, a pair of bolts 32 are employed, one on each side of'the center sill construction and extending parallel with the center sill and mounted in the respective sets of diaphragms 13. The bolts 32 are placed in line with the ends of the keys 81 so that it is necessary to remove one of the bolts before the keys 31 can be removed.

As clearly shown in Fig. 2, the upward extension 24 of the body center bearing member A is notched as indicated at 38-33 to'correspond with the cross section of and to accommodate the keys 31. I Vith this construction, it is evident that the center bearing block A is detachably secured to the underframe of the car and yet can be readily removed by taking out the keys 31. In this connection, it will be observed that either bolt 82 may be readily removed since they are located outside of the center sills, and it is a comparatively easy matter for a man to insert his arm through any one of the diaphragm openings 14 and remove the keys 31.

Preferably, the center bearing block A is provided with laterally and longitudinally extended flanges 34, the latter having up-turned edges 35 adapted to engage the lower angles 11 and front and rear edges of the filler casting 26 at the bottom of the latter, as shown in Figures 1 and 2.

To detachably pivotally lock the body and truck center bearing sections, I employ a sectional three piece center pin. The latter approximately semi-circular said members 36 having laterally extended flanges atv the top and bottom ends thereof comprises two side members 3636 each of as indicated at 3738, said flanges taking over co-operating shoulders 39 and 40 formed respectively at the upper end of the center bearing block A and the lower end of the center bearing section 18 of the truck bolster. Said members 36 with their flanges 37 and 38 (see Fig.4) are so proportioned that, when the two are placed in face to face 7 contact, they may be inserted through the center pin openings and, after being spread cross section,

apart, are held in separated operative con dition by a spreader plate 41 preferably shouldered at its upper end as indicated at 42, best shown in Fig. 4, so as to rest upon the top end of the bearing block A.

In the use of my invention, the center bearing block A and locking center pin will first be properly assembled with the truck bolster. The car body is then jacked up and the truck with the center bearing members assembled as indicated, run beneath the car body and the latter allowed to drop over the upward extension 24 of the center bearing block A. The keys 31 are then applied and finally the retaining bolts 32. The reverse procedure is adopted when it is desired to i,

merely illustrative and all changes and modifications are contemplated that come within the scope of the claims appended hereto.

I claim:

1. In car construction, the combination with a body bolster and a truck bolster, the

latter having a center bearing section as'.

sociated therewith; of an independent body center bearing block detachable with respect to the body bolster, said block and body bolster having opposed shoulders thereon; and means, insertable and removable through said shoulders transversely of the car, for locking said center bearing block to the body bolster. i

2. In car construction, the combination with a body bolster and a truck bolster, the latter having a center bearing section rigidly associated therewith; of an inde; pendent body center bearing block detach able with respect to the body bolster; and

means, insertable and removable transversely of the car, for locking said center bearing block to the body bolster, said. horizontally disposed keys means including each extending through both the center sills.

3. In car construction, the combination with a body bolster and a truck bolster, the latter having a center bearing section rigidly associated therewith; pendent body center bearing block detachable with respect to the body bolster; and

keys of a length to extend across said block,

insertable and removable transversely of the. car, for locking said block to the body bolster.

4. In car construction, the combination with a body bolster and a truck bolster, the

of. an indelatter having a center bearing section rigidly associated therewith; of an independent body center bearing block detachable with respect to the body bolster; keys, insertable and removable transversely of the car, for locking said block to the body bolster; and independently carried retaining means at the ends of said keys.

5. In car construction, the combination with the center sills and a body bolster, the latter comprising spaced pairs of iaphragms at each side of the center sill and a center tiller block, one of said diaphragms having an opening therein adjacent the corresponding center sill; of a truck bolster having a center bearing section permanently associated therewith; a body bolster center bearing block detachable with respect to said tiller block; and means for locking said center bearing block to the filler block, said means being accessible through said opening of the diaphragm.

6. In car construction, the combination with the center sills and a body bolster, the latter comprising spaced diaphragms at each side of the center sill and a center filler block, the latter having a vertical opening therein and transversely extending openings, the center sills being apertured opposite said transverse openings; of a body bolster center bearing block having an upward extension insertable Within said verti cal opening of the filler block; and transversely extending keys Within said trans verse openings of the filler block and center sill openings, said keys engaging shoulders provided on the center bearing block for detachably locking the latter to the tiller block.

7. In car construction, the combination with the center sills and a body bolster, the the latter comprising spaced diaphragms at each side of the center sill and a center bolster filler block, said diaphragms having openings therein and the filler block having a vertically extending opening and transversely extending openings; of a truck bolster having a center bearing section permanently associated therewith; a body bolster center bearing block co-operable with the center bearing section of the truck bolster, said bearing block having an up ward extension fitting within said vertical opening of the filler block; a detachable sectional shouldered center pin extending through the center bearing section of the truck bolster and said bearing block and arranged to prevent accidental vertical separation thereof; keys extending horizontally through the center sills and through said horizontal openings of the filler block, said keys being disposed within the planes or" the diaphragms and accessible through said openings of the diaphragms, said keys detachably locking said bearing block to the filler block.

In witness that I claim the foregoing I have hereunto subscribed my name this 3rd day of January 1923.
